Wait a minute... Are we sure that this is actually Neville's grandmother? It could in fact actually be his grandfather as the BTS-section note about the Danish version suggest. Neville does only say "gran". Just want to be sure. --DCLM (talk) 10:26, June 29, 2013 (UTC)

It's definitely his gran - Neville says that he saw his grandfather die; he confirms this in Order of the Phoenix when Umbridge asks him why he can see Thestrals. HarryPotterRules1 (talk) 10:50, June 29, 2013 (UTC)
Is it specified when he died? It's been a long time since I read the books. If not we can only go by his article on the wiki which states "ca. 1980 - 1995". --DCLM (talk) 11:13, June 29, 2013 (UTC)
The term "gran" most commonly means one's grandmother. -- 1337star (Drop me a line!) 14:57, June 29, 2013 (UTC)
